ing ooit Comprising o holder for the hair circular opening 18 which registers with the a lWttvmg or ourlmg rod mounted upon the openings 8 of the shield and 11 of the bottom holder and about which the hair is wound plata and a heater. My invention is directed to The holder and the shield are secured toan improved holder and insulating or sheldgather by screws `21 Which pass through Suit- 100 able openings therefor in the shield, the cork layer or pad and the top and bottom plates 17 and 10, respectively,.of the holder. lThe heads of the screws 21 are preferably seated within the asbestos layer and, in order to provide additional insulation for the heads, small cork disks 22 are positioned against them, the disks 22 being retained by the asbestos layer 4f. It has been found in practice that the screws 21 become heated during the use'of the device and that the additional insulation provided is desirable.

l/Vithin the slideway 12 of the bottom plate 10 is provided an oblong opening23 for .the

reception of the oblong tapered head 24 ofV the screw 25 which passes upwardly through Vthe clamping member 1l within the reduced portion 26 of the keyhole opening 16 and through the opening 27 of the top plate 17 so as to permitthe lower interiorly threaded end of the curling or waving rod 28 to thread Y thereupon.

' the patron a block of hair is passed through through the holder.

the opening 8 of the shield 3, thence through the opening. provided therefor in the cork layer 9 and thence through the openings 11 of the bottom plate 10 of the clamping member and 18 ofthe top plate 17 the clamping member being positioned within the -s'lideway 12 so that the circular portion 16 of the opening 16 is in registry with the openings 11 and 18 whereby hair may be readily passed The shield vor insulating pad 3 is preferably pressed tightly against the scalp, the hair is drawn tautly through the openings in the shield, cork paid and holder as aforesaid and the clamping member 13 is then pressed inwardly within the slide- Y way 12 thereby causing the hair to be pinched or clamped and securely held in the reduced opening thus formed, the opening 16 therein then being out of registry with the openings 11 and 18, theeXtent of the opening in the Aclamping member being reduced to the thicl'- ness of the hair passing therethrough. The

'- waving rod 28 is then threaded on the screw 25 until the plate 10, clamping member 13 and plate 17 are tightly drawn together. The hair is then wound spirallyabout the waving rod 28 as `shown in Fig. 1, following which a strip, known in the art asa striX', of flannel or other suitable material which has been Vdampened in a suitable steaming solution is tightly wound spirally about the hair. The heater '29 is now superimposed over the waving rod with the hair and llannel strip or striX wound thereabout, a suitable opening being provided in the top of the heater for the passing therethrough of the waving rod 28, the bottom of the heater being seated upon the top of the holder as shown in Fig. 2. The rod 28 is provided with a circumferential notch 30 within which a spring loch 31 engages to hold the heater firmly seated against the holder and provide a substantially airtight joint therewith. The heater is of a well known type and is provided with resistance coils which are heated by electric current supplied thereto by wires 32, 33 which are connected with a lighting circuit or other source of current.

Y rlhe shield 3 is preferably circular in form and is of a greater diameter than the holder whereby the metal parts of which the latter is comprised are effectually prevented from coming into contact with the hairand scalp and burning them, it being understood that when the heater is operating steam is generated from the striX and the metal parts of the holder become heated. By my improved holder, it will also be observed, escape through the holder to the scalp of the steam and the liquid resulting from condensation is prevented inasmuch as the opening extending from the `holder through the shield is scaled by the clamping member in its pinching contact with the hair, as above described. It will now be seen that the waving rod, holder and shield may be assembled intoa Vunit before applying' to the headv of the patron and the hair of a block may then be readily pulled through `openings provided therefor in the shield,rcork layer and holder and the clamping member moved into pinching relation with the hair; the waving rod, partly threaded upon the screw 2 5, is

then secured against the top plate of the holder, thereby drawing-the shield, cork'layer' and the holder partstogether 'and firmly securing the hair in the holder as desired; the hair is then wound about' the waving rod, the strix applied thereto and the heater positioned. 1 Y y In practice, the necessary number of wavunits are applied to the hair at the sam-e time and they are operated simultaneously.

Owing to the protection afforded by my invention against scalp Land hair burns', the employment of an attendant for .each patron to operate an air cooler is made unnecessary.

Furthermore, a single operator is capable of attending to four or more patrons at the same time while hitherto an ope-ratorhas been required for each patron. The labor cost has accordingly been greatly reduced and with entire safety and less discomfort to the patron.

While l have herein described with parstruction and arrangement of parts as the same may be modified and varied in minor particulars from those shown in the drawings and herein described without departing from the spirit and scope of the invention as defined in the appended claims.

Having thus described my invention, I claim and desire to protect by Letters Patent of the United States:

1. In a device of the class described, a hairholder comprising a top plate, a` bottom plate, a slideway within said bottom plate, a clamping member within said slideway and slidable therein, said plates and clamping member being provided with openings through Which the hair passes, said clamping member being adapted to be moved to intersect the passage formed by said openings in said plates Whereby the hair is compressed and securely held.

2. In a device ofthe class described, a hairholder comprising a top plate, a bottom plate, a slideway within said bottom plate, a clamping member slidable within said slideway and means for locking said clamping member within said slideway.

3. In a device of the class described, the

, combination of a heat insulating member, a

hair-holder secured thereto and comprising a top plate, a bottom plate and a clamping member for securing the hair against withdrawal from the holder, a screw passing through said plates and clamping member and projecting above the top plate and a waving rod threaded upon said screw and about which the hair is adapted to be wound.

4. In a device of the class described, the combination of a heat insulating member, a hair-holder secured thereto and comprising a top plate, a bottom plate and a clamping member for securing the hair against withdrawal from the holder, a screw passing through said plates and clamping member and projecting above the top plate and a waving rod adapted to be threaded onto said screw to draw said plates and clamping member firmly together and secure said clamp-y ing member against movement.

In witness whereof I have hereunto set my hand this 2nd day of April, 1928.
